This isn't the first time The Wrecking Ball singer has been seen getting cosy with Liam's relatives; she also holidayed with Liam's actor brother Chris Hemsworth and wife Elsa Pataky, who she's becomes firm pals with. In April Miley and Elsa even got matching custom wave tattoos, perhaps in honour of the surf loving Australian brothers.

According to editors at Us Weekly, Miley and Liam are planning to exchange vows in his home country of Australia.

During a late April trip to visit the 26-year-old actor’s family in Byron Bay an insider told the publication: "They were discussing potential venues and looking around."

The couple, who met while filming movie The Last Song in 2009, reunited after ending their engagement in 2013. While neither of them have made an official statement, Liam told Entertainment Tonight: "Everyone's happy. I'm happy. Yeah... I just find it's easier to not talk about my personal life because usually I say the wrong thing, so it ends up just complicating things more. So, I feel like it's better not to talk about it."
